OMIA 000483-37174 : Polled/Horns in Ovis canadensis

In other species: cattle , goat , sheep , water buffalo , kouprey , domestic yak

Possibly relevant human trait(s) and/or gene(s) (MIM number): 110100

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: There is substantial variation in the extent of horn growth, making classification difficult. However, in general, the presence or absence of horns can be attributed to the action of two alleles at an autosomal locus. The type of gene action varies considerably between and among species.
